Rain X fluid and Low Washer Fluid Sensor

[MoparDave]

I know this thread is old, but this rain-x issue happened to me. It left a gooey coating in my windshield washer tank and on the sensor causing a low washer fluid warning.

Here’s how I fixed it by only popping the hood and flipping open the washer fluid cap.
1) Pumped out all the washer fluid with an auto siphon from Auto Zone ( 11 bucks)
2) Washed the tank out repeatedly with my garden hose.
3) Added a mild soap scum agent( think scrubbing bubbles) to tap water, agitated with garden hose. I let it sit an hour and then siphoned it out.
4) Washed throughly and repeatedly with garden hose ( paying attention to agitate where the sensor lies) and siphoning repeatedly until clear and clean.
5) Refilled with the cheap blue stuff.

Result was a clean reservoir and no more “washer fluid low” warning light.

@NachoRuby sorry for digging up an old thread but can you explain how to disable the sensor in JScan? I just picked up my gladiator and JScan and see a lot of things posted here that I’m not seeing on JScan.

I've been using the ORANGE stuff since it came out 2000? in maybe 10 vehicles of many brands and never any problems.

I have been using the orange stuff for years also. However, I had this same issue with my ‘22 gladiator. It coated the tank and sensor leads. It was a pain to get the reservoir out and back in. Then I disturbed the pump and had to do it all again.
I’ll never buy the orange rain-x again. Happy to see someone else posted about it. lol I never would have thought about it. I got on here just to post about it. It took almost 3 years to cause the issue.

My "fix" to clean the sensor is a shot of dish washing detergent. Dawn works good for it, but defeats the RAIN-X purpose.

Learned not to use it many MOPARs ago. I stuck a round brush with a flexible handle like for cleaning a drain. Stuck it in by the sensor and scrubbed it best I could. Syphoned it down to almost empty , filled it up with any brand but rainX and all was good. Learned my lesson

I started using Orange in my 2000 Dakota never had a problem. It's been in my 2021 Gladiator since new, I drained the factory fill crap immediately.
Still no problems and using it still in all my other vehicles.

I've only used the Orange Rain-X 0° All Season 2 in 1 pre mixed illegal in the state of California year round in mine since it was new in 22 and haven't had any issues. I use the washer fluid almost every day but never let the reservoir get empty. When I top it off its usually around half full.

Before my Gladiator it was also the only washer fluid I used in my 04 TJ since 2007 and never had any issue in that either.

Those that have had issues do you mix different types of fluid together, causing gelling like some coolants will do if mixed or let the reservoir go empty before refilling and it maybe dries up causing the coating?

I've had it happen with any "Rain-X" types of washer fluid in my JT. Never been a problem in my 05 Wrangler or XJ. . . No sensor in Wrangler but one in my old XJ, it always shows low if not filled to top. Been using Rain-X since early 90's first vehicle I've had it gunk up a sensor.

Its interesting how some people have issues and others don't even with long term use. I brought up my TJ because some have mentioned they've had issues with the Rainx clogging lines and nozzles.

I live NH the blue stuff freezes and the true winter stuff doesn't clean been Running rain X fluid for over 30 years. I Have had one sensor in a Mini go bad. I took it out I cleaned it with contact cleaner put it back in and was on my way

My 05 Wrangler spray nozzles have failed not from windshield solvent but sun and heat cycles I had to replace them. Now the motor has gave up. Still pissed about not keeping the single washer bottle mine came with. When I bought a use hardtop I bought a OEM one for hardtop with double washer motors.

I've used nothing but Rain X green and orange for 4 years without problem. To be honest, I didn't know the jug even had a sensor but I use it often enough that I keep it filled

It seems to be hit or miss on the sensor getting gunked up. Some times mine does then other batches it doesn't.

I've had sensors fail in 3 different vehicles using RainX just months after starting to use it. Reading here about the different results people are having. Makes me wonder if it's location, some different between lot numbers, made in different plants, storage, shelf life, or something else.
